Theory/Model: TAM



Technology Acceptance Model

The Technology Acceptance Model (TAM) was initially presented by Davis (1986), while conducting his doctoral thesis. This model is an adaptation to Theory Reasoned Action (TRA) (Ajzen & Fishbein, 1980; Fishbein & Ajzen, 1975), where the main objective is to explain the behavior of the use of information systems (Almeida, 2002; Davis et al., 1989). Later, in 1989, with the works developed by Davis, Bagozzi & Warshaw (Davis et al., 1989) the TAM was finally conceptualized, where it gained visibility. The Technology Acceptance Model intends to explain the behavior of the users of a computer system, claiming that the use of the computer system depends directly on the intention that the individual has in using it (Almeida, 2002). TAM refer that Behavioral Intention to Use results from the influence of the user's Attitude Toward Using and Perceived Usefulness. As a result, Attitude Toward Using is influenced by two essential factors, Perceived Usefulness and Perceived Ease of Use. Davis et al. (1989) consider that the Perceived Ease of Use can also affect the Perceived Usefulness of the system, while both are influenced by External Variables. The most current version is TAM 3, which presents a complete nomological network (integrated model) of the determinants of IT adoption and use by individuals (Venkatesh & Bala, 2008).
